  There is no single project changelog page. buildpacks.io/releases/ — which apis.yml previously
  advertised as ReleaseNotes — returns 404; the real dated record is the per-repository GitHub
  release stream for the lifecycle and the pack CLI, plus the versioned Deprecations sections of
  the specification.
